An object with a mass of 5.69 kg undergoes an acceleration of -4.7 m/s^2 for a period of 5.8 seconds. It then undergoes an acceleration of 6.9 m/s^2 for a period of 8.7 seconds. If the initial velocity of the object is 1.51 m/s and it first experiences acceleration when it is at the origin, plot by hand a graph the force, velocity, and position as functions of time. Explain why your graph look the way they do and include...
